Get-PendingFederatedDomain

The Get-PendingFederatedDomain cmdlet is used by the Exchange admin center to display a list of pending federated domains for the federation trust for your Exchange organization. You shouldn't use this cmdlet to attempt to manually configure a federation trust.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Federation trusts" entry in the Exchange infrastructure and PowerShell permissions topic.
